That is all bags (Aircrafts) arrive from a limited number of tunnels (Thresholds) and can reach any standing passenger (ParkPos) using a single belt (routing flow). It does not matter where the passenger stands nor what order the bags arrives in; if you wait long enough all bags will meet their owner, (unless you are at Heathrow). | That is all bags (Aircrafts) arrive from a limited number of tunnels (Thresholds) and can reach any standing passenger (ParkPos) using a single belt (routing flow).

An advantage AI aircrafts have over bags is that they can ‘transfer’ from one belt to another if a segment belongs to more than one belt/route. Putting it visually, a typical routing flow will resemble something like the image on the right. | An advantage AI aircrafts have over bags is that they can ‘transfer’ from one belt to another if a segment belongs to more than one belt/route. Putting it visually, a typical routing flow will resemble something like the image on the right : ‘Belts’ in green rotate clockwise, red ones rotate counter clockwise, segments in blue provide access in and out of the belts. The main belt along the northern runway includes bypasses allowing an aircraft to quickly reach the other side of the belt without having to travel its full length. | ||
Using the diagram, you can pick any combination of one runway access (threshold or intermediate vacating point) and one parking position and realize you can always find a unique route from A to B and another unique route from B to A without ever coming across an intersection, always using "Y" shaped merging lanes. | |||

An additional benefit of the technique is visible when comparing the routing flow diagram and the base network image in the previous section: A groundnet with proper routing uses less nodes and segments than a full network, saving you time during the building phase. In fact, as you get more familiar with the technique you will realize it is a good idea to map your routing flow before building your groundnet so you create just enough nodes and segments. | An additional benefit of the technique is visible when comparing the routing flow diagram and the base network image in the previous section: A groundnet with proper routing uses less nodes and segments than a full network, saving you time during the building phase.

It is also important to know that you do NOT need to mark each and every segment as "unidirectional" but only the ones forming your Y shaped intersections. | ||
